PROTECTOR FOR THE ENDS OF BEAMS.

SPECIFICATION forming part of Letters Patent No. 462,357, dated November3, 1891.

Application filed June 2,1890. Renewed September 15, 1891. erial No.405,741. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM KENNIsH, a citizen of the United States,residing atI-lrooklyn, Kings county, New York, have invented certainImprovements in Protectors for the Ends of Beams, &c., of which thefollowingis a specification.

My invention relates to that class of devices employed .in buildings andother like structures for incasing the ends of beams set in the walls ormasonry thereof in order to protect said ends from deterioration anddecay from the moisture of the masonry, as well as from the attacks ofinsects and the like.

The object of my invention is, in part, to provide a protector of thisgeneral character wherein sufficient space shall be provided about theend of the beam to afford free access of the air, in part to provide aprotector which shall be applicable to beams of varying cross-sectionwithin limits, and in part to provide a protector which shall hold thebeam firmly in place when once set about the end thereof.

In the accompanying drawings, which serve to illustrate my invention,Figure l is a perspective View, on a reduced scale, of a beam providedwith my protector, set in the wall of a building. Fig. 2 is aperspective view, on a larger scale, illustrating the two like parts orsections of my protector.

In the drawings, A represents my improved protector as a whole, B thebeam, and C the masonry of the wall.

Ct a represent the two sections or halves of my improved protector,which are or may be substantially like and equal. Hence a description ofone section will suffice for both. The section a consists of a back orbase a, from which project, on two adjacent sides or edges, the sideflange a and the top or cover flange a The side flange a is provided onits inner face with raised transverse ledges or serrations a, whichextend over its entire inner surface.

In applying my improved protector to the ends of beams in buildings themasonry or brick-work is laid up to the level of the tier at which thebeam is to be set and the beam is then placed. \Vhen properly placed andset on the last tier of brick, the two sections of my protector areapplied over the end of the beam and the brick is laid on either sidethereof, as usual, care being taken to press the sections well together,in order to hold the g sirable in some cases to spread the last tierofbrick below the beam and to fill up the space between the sections ofthe protector with cement.

As will be readily observed, my protector, being preferably constructedof concrete, burned clay, or other such material, may be applied tobeams of varying dimensions. Where the beam is too thick, the spacebetween the sections is filled with cement and where the beam is toonarrow the flanges of the sections are broken away to fit.

The ledges or serrations (4 serve two useful purposes. They hold thebeam when set firmly in position away from the side flanges thusallowing free access of air about the sides of the beam end for purposesof ventilation. These ledges may of course be provided on thecover-flange a and base a, as well as on the side flange; but this isnot usually necessary.

My protector has certain important characteristics, namely: Its sectionsare plain or unprovided with any curved lips on their faces for securingthem together when applied, and they are disconnected, so that they canbe set at any distance apart that may be required to adapt them to thethickness of the beam to be protected. The planes of the faces of thesections adjacent to the dividing-line between them are perpendicular tothe base of the protector, or substantially so, and each section isprovided with acover-flange to take over the top of the beam.

In manufacturing my improved protector I prefer to so proportion it asto replace some certain number of brick, both as regards its width,thickness, and height; but this is not essential, as the spacesremaining after the protector is set in place may, as stated be: fore,be filled with cement or ordinary mortar; nor is it essential to myinvention that my ICO ' having a cover-flange a to take over the top ofthe beam when the protector is in place;

2. As an improved article of manufacture, a sectional protector for theend of a beam or joist, having back, side, and top flanges only, wherebythe protector may be applied after the beam has been placed and set.

3. As an improved article of manufacture,

a protector for the end'of a beam or joist, consisting of two sectionsor halves, each having back, side, and top flanges, the planes of-thefaces adjacent to the dividing-line between them being substantiallyperpendicular to the base of the protector.

4. As an improved article of manufacture, a sectional protector for theend of a beam or joist, consisting of two like sections having back,side, and top flanges only, and provided with integral ribs a on itsside flanges, said ribs having convex or rounded surfaces, substantiallyas set forth.

In witness whereof I have hereunto signed my namein the presence of twosubscribing witnesses.

WILLIAM KENNISH.
